Sign of tunnel coupling in barrier-separated Bose-Einstein condensates and stability of double-ring systems
Joachim Brand, Tania J. Haigh, Ulrich Zülicke
We revisit recent claims about the instability of non-rotating tunnel coupled annular Bose-Einstein condensates leading to the emergence of angular-momentum Josephson oscillation […
